Hi All, We've created our own auth plugin in Java to authenticate against Oauth2 of Azure. This is working fine with Neo4j 3.5.18. We're planning to migrate to Neo4j v4.2 and running into an issue when trying to use our plugin. A simple local test wi...
Hi all, I'v checked the source of KSpanningTree.java, and find that there may be a bug at the end of the compute() function. I think that a k spanning tree shoud be a tree grows from the started node in a serialized way, and couldn't be implemented i...
I am quite new to using Neo4j. I was trying to invoke the cyphershell for the sample project provided in Neo4j locally using Neo4j desktop terminal, but seem to be getting this error. I'm not really sure what I'm doing wrong.
I am trying to create a graph where nodes are products and they're linked by the ids of customer who've bought both products. The basic idea is contained in "Graph-Based Structures for the Market Baskets Analysis", and the key figure is here: Eventu...
Hello, I have this cypher query: MATCH p=(no {name:'nodeName'})<-[:enfant*0..]-(parent:application) unwind nodes(p) as n unwind relationships(p) as r with collect( distinct {id: id(n), name: n.name, labels: labels(n)}) as nl, collect( distinct {sour...
How do the embeddings of GDS handle categorical attributes and different relation or node types? From the examples of 6.7. Node embeddings - Chapter 6. Algorithms it looks like the projection should contain equal types of nodes and relations only and...
Hi, Trying to craft a simple query where the depth of the relationship is subject to user input. My search phrase is Find $numlevels levels away from $cpcstart where $numlevels is defined as an integer and $cpcstart is node name property key Match p=...
Hi everyone, I'm pretty new to neo4j and I got stuck on a query that I could not figure out the best way to do it. Here is my graph model, where an author has multiple co-authors and writes multiple publications My need is the following: find the n...
Hi, I am building a tree-like graph of network based on CIDRs, like this (simplified) example: Red nodes represent CIDRs, for example 10.0.0.0/27, 10.0.0.0/28, etc. Brown nodes represent that /32 IPs, for example 10.0.0.0/32, 10.0.0.1/32, etc. Due t...
Hello community! I am new to Neo4j and using Cypher. I am trying to find circular money flow from using the approach similar to one mentioned in the following blog. The approach works very much fine when my graph has 20M nodes and 21M relationships (...

Hello! I am a newbie to Neo4j. I am using apoc.periodic.iterate to create a new relationship between the existing nodes when a certain condition is satisfied, with {batchSize=100000, parallel:false}. This throws me an error java.lang.OutofMemoryError...
Guys, I am new to Neo4j platform and pretty much noob in writing cypher queries. I have a query which creates a brand, branches and checkoutTypes associated with it. CREATE (brand:Brand { id: apoc.create.uuid(), ...
Hi, i'm trying to import xml with predefined namespaces <xelement:some_element></xelement:some_element> is there a way to keep full tag in apoc.import.xml like "xelement:some_element" instead of imported "some_element" tag?
Hi, I have a bit of a challenge around optimising a query to run more efficiently, as currently it takes too long. Just some background: The database size is 90m nodes, 700m relationships - although this query is being tested on a much smaller sample...
